' Strainers, of wpich the following is a spec-i fication. 1 i My invention relates to improvements 111 '10 gasolene strainers for use in the line of the supply for internal combustion engines on automobiles and. motor cycles, and the object fiofmy improvement is simplicity and econ- Q 1ny in construction and convenience and oi 115 ficiency in use.

In the accompanying drawing :-liigurc l is" afside elevation of one form of my im- PiOVed gasolene st ainer. Fig". 2 is a sectional view of the same. F'g, dis a side ele- [ration of another form. of my improved gasolen'e strainer. Fig. 4 is a sectional view the same. I My strainer is an elongated egg-shaped structure and comprises two main. members res ectively a bottom or lower member B F an an upper'or'top member C that are ad :justably and separably connected together,

having an inlet suitable for being con nectedgto the gasolenc supply tank, an out- 30 1et"1 1 .suitable for being connected to the "L; carburetor and a strainer proper 12 bridging the interior structure. The bottom member B and top member (1 are hemi-spherieal structures and are joined adjacent the equatorial plane by a joint 13 of special character comprising an inner conical portion [and an outer radial or plane portion which .jointis carefully ground and assures a tight 'lfitso'i'as to prevent leakage of gasolene when the parts are held engaged in normal position and also will permit turning the said bottom member B and top member C axially relatively one to the other so as to permit of changing the angular positions of the inlet 10 and outlet 11 relatively one to the other. An axially positioned screw D serves to secure the members B and C together in a manner to be described.

The bottonifmember comprises a hemisphericalshell-like structure having the inlet lllextending radially from the body portion 'andh as' the top shaped to form one of the members oi the joint 13 comprising .the conical portion 14 on the inner side and the flat portion 15 in the radial plane on the outer side. The interior. at the bottom is provided with a boss 17 that extends axially upward. An axial hole or bore 19 extends through the boss 17 and downwardly through the bottom wall of the bottom member and which is screw threaded. Radial inlet holes 20 connect the interior of th body of the bottom member B with the bore 19, and serve thereby to provide connections leading laterally from th said interior to saidbore l9,

7 The upper member C comprises a hcmispherical shell-like structure having a bottom edge that is formed the counter part of the conical portion i l and radial portion 15 of the bottom member and co' perates therewith to form the joint '13 and is provided with the outlet 11 extending radially from the body portion 21 thereof. The top at the pole is provided with an axial hole 22 which is preferably recessed or countersunk suitably to form a seat for the bottom side of the head 2-2 of the screw or bolt D and the same may on age with the said head 24- directly or a pac ring washer F may be interposed therebetwecn. A sleeve 25 eX- tends axially downward from the hole 22 for a greater part of the body portion 21 and serves as a guide to give axial direction to the screw 1) when inserted in the hole 22 and suitably to guide the same to the threaded bore 19 in the boss 17 and also prevents damage to the strainer proper 12 by the insertion. of the screw D. ."lhe said screen or strainer proper 12 is positioned in the upper member C and comprisesa sheet of wire gauze of suitable mesh and of proper size to bridge the space across the interior of the body portion, being provided with a central hole to admit the sleeve 25.' The screw or bolt D is of suitable length to engage the hole 22 of the upper member C by the head 2i and the lower member B by the threaded lower end engaging the threaded bore 19 of the boss 17 and to hold the said members en gaged at the joint 13. When the said members are held together in the manner dethe gauze strainer 12,-and the bottom portion B operates as a reservoir to collect water and foreign matter as mentioned. The angular relation of the inlet and outlet may be changed as desired, the screw D being preferably loosened and again tightened in effecting any change in adjustment.

In the type described flushing is effected by raising the screw thereof, below the lateral holes 20, thus opening a passage from the interior space through the bottom wall of the bottom member B.

This type of device provides a straining device that is compact, safe and reliable and permits of easily flushing without separation of the top and bottom member.

The joint 13 as stated is a ground joint, the greater portion thereof consisting of the taper or conical portion 14 the radial or plane portion 15 being of relatively small ex tent and is provided partly for the purpose of forming a broken joint and also to provide a finish. so that the exposed portion of the jointiwill be essentially a true circle or at least will be in a single plane and essentially at right angles to the axis or in a radial plane. Both portions of the joint are ground and cooperate to effect a gasolene tight joint.

The type of device shown is suitable either for automobiles or motor cycles.

In Figs. 3 and 4 are shown another modification of my gasolene strainer that is suit able for a diminutive type, such as is adapted for use with motor cycles, and which has advantages over the type shown in Figs. 1 and 2 in being better adapted to be made tight against leakage of gasolene. In this D in the lower portion screw .D'-. The lower member B" is'provided at the lower pole with the tapered hole v 22 suitable for receiving the head 24 of the holding screw D preferably with the packing washer F interposed therebetween. In this type the flushing is effected by loosing theholding screw a little so as ta drop the headQ P of the screw Daway from the hole 22 and permit the escape of water and foreign matter from the interior.

I claim as myinventionz- A gasolene stra-iner comprising a pair of m A hemispherical members having edges in abutment, and a strainer proper bridging the open interior space of one of the saidmembers, and an inlet connection provided on one of the said members and an outlet connection provided on the other of the-said members, and securing means comprising a screw axially; positioned and operat ye" to hold the said memberstogether, onebf the said members provided with an axial flush-' ing outlet,.and the said screwrnormally filling the said flushing outlet.
